PIM-SM_join_prune.cap 3.8 KB

Submitted Sep 14, 2009

A host on R4's 172.16.20.0/24 subnet requests to join the 239.123.123.123 group. R4 sends a PIMv2 join message up to the RP (R1). Subsequent join messages are sent every 30 seconds, until R4 determines it no longer has any interested hosts and sends a prune request (packet #45). PIMv1 RP-Reachable messages for the group are also visible from R1.
